The empirical Bayes estimation for the parameter of the Gamma distribution families in the case of NA samples;
NA样本情形下Gamma分布族参数的经验贝叶斯估计
Gamma distribution families are often applied in survival data analysis, so it is very significant to estimate its shape parameter.
Gamma分布族在生存数据的研究中应用很多,对其形状参数做出估计是非常有意义的,黄江平给出了独立同分布样本下标准伽玛分布族参数的EB估计的收敛速度,在更一般的情况下,本文讨论了Gamma分布族在平方损失下参数的贝叶斯估计,利用同分布负相协(NA)样本构造了经验Bayes(EB)估计量,在适当条件下证明了EB估计的渐近最优性,并获得了其收敛速度,比黄江平的文章更有普遍性和实用性。
In this paper, the Johnson distributions family is applied to the method and fits the return data.
矩匹配方法是用来求解非线性风险度(ValueatRisk,简称:VaR)的一种普遍性方法,它是先假定样本经验分布服从已知分布族,然后运用矩匹配估计方法估计相应的参数,得到资产回报样本的密度函数,再计算风险度VaR;本文采用的Johnson分布族是矩匹配方法的直接应用,并且计算出来的结果与局部Monte Carlo结果进行了比较,并通过实证分析认为这种方法是一种良好的计算非线性VaR方法。
